Thrashing and Cleaning Grain.

A. LINHART AND S. MCOLAIN, OF FULTON, OHIO.

oonsriwo'rrolv or Specification of Letters Patent No.

To all whom it may concern Be it known that we, ADAM LINHART and SAMUEL MoCLAIN, of Fulton, in the county of Stark and State of Ohio, have invented a new and useful improvement on J A. and H. A. Pitts machine for cleaning grain and clover-seed; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of said machine, reference being had to the annexed drawings, making a part of this specification, in which Figure 1 is a perspective drawing of the original invention of the Messrs. Pitts, with the improvements which your petitioners claim attached to the machine. Your petitioners therefore, hereby disclaim the inven- I tion of those parts of the original machine represented in said drawing, and only claim that they have invented a new and useful improvement on said machine, and they do hereby declarethat the following is a full, clear, and exact description of the construction and operation of the same; reference being had to the annexed drawings marked figure three, making a part of this specification, and which said drawings represent by sections, the improvements made by your petitioners on said machine. In which A, A, is a longitudinal view of the upper or'wire belt, and is constructed in the following manner. It is composed of two hundred cross sloats, thirty inches long, one inch in width, and five-eighths of an inch thick: through which the wires are put, equidistant from each other, two inches, extending from sloat to sloat, and forming an open space of one inch, when working in a straight line. The belt is thirty-four feet long. To each end of each of the sloats, there is a block attached, two inches in length, one and a fourth inches in width, and three-fourths of an inch in thickness. The ends of the belt are fastened together by two small screw bolts. The sloats are connected together by a leather strap on each side of the machine, tacked to the blocks, on the under side; the blocks being curved so as to accommodate them to the pulley over which they pass. The use and application of this belt is to cause a separation of the grain from the straw immediately on leaving the cylinder; by which operation the straw is carried by the belt to the summit of the machine, and there discharged, so as not to interfere with together, but vary in size.

the action of the fan. The original machine GRAIN-CARRIERS.

having but one belt, the advantages possessed over it by the addition of the upper or wire belt, consists in a perfect separation of the grain from the straw; thereby preventing the straw from following the grain to the fanning mill. lVhereas the original machine having but one belt, could not cause so perfect a separation, but must necessarily discharge a portion of the straw with the grain into the cleaner, thereby obstructing the performance of the fan. B, B, is a taper pulley through which the shaft of the fan extends, having a taper of one inch: being eight and a half inches in diameter at the lame end and seven and a half inches in diameter at the small end thereof; its length being six inches with four grooves cut in it, equidistant from each other so as to admit a twisted strap, by which means the motion of the fan is increased or diminished, and its performance regulated, which is an improvement on the original machine.

C, C, and D, D, are two shaker shafts, with cylinders thirty inches long, and five inches in diameter, with two rows of wire teeth winding longitudinally around the cylinders, and inclining backward, C, C, having sixteen teeth in the two rows placed opposite and equidistant from each other and D, D, having fourteen teeth in the two rows, placed in the same manner, and breaking in the open space of the teeth of C, C. Through each of the cylinders, passes an iron shaft seven eighths of an inch square, of suflicient length to admit of pulleys on each end of the shafts. Pulley E, on shaker shaft C, C, is fourteen inches in diameter and three inches thick. It being the pulley by which the thresher is connected with the cleaner, by a strap thrown over pulley E, and a three inch pulley attached to the shaft of the cylinder of the thresher. Pulleys F and G, on shaker shaft, C, C, are connected Pulley F, being four inches in diameter, and two inches and a half on the surface, and is designed for driving the elevators. Pulley G, is ten inches in diameter and two and a half inches on the surface, and connects with shaker shaft D, D, by a strap at pulley H. Pulley H being'of the same dimensions of pulley G. To the outside face of pulley G, fly wheel J, is attached, which is made of cast iron with a rim of an inch and a quarter surface, and is twenty inches in diameter. Pulley J on shaker shaft D, D, is designed for driving the under belt, and is five inches in diameter, and two and a half inches on the surface. Pulley K on shakershaft D, D, is the same in size with pulley J, and is usedand designed to drive the upper belt. The pulleys on both of the belts, being one foot in diameter, and two and a half inches on the surface. Pulley L on the shaker shaft D, D, and connected with pulley K, is six inches in length, and having a taper of one inch, being six inches at the large, and five inches at the small end thereof in diameter, with four grooves cut in it, equidistant from each other, and is used and designed for driving the fan, and is connected with the pulley B, B, by a twisted strap.

The peculiar advantage to be derived from the additional shaker shaft, (the original machine having but one, and that one constructed of boards, and the substitution of the wire teeth for the boards) are as fol lows: The board shaker shaft in-the original machine shoved the straw in a body along thebelt, whereas the cylinder shaker, with the addition of another shaker, and the substitution of the wire teeth, cause a more perfect separation of the straw from the grain, and thus save a large amount of grain, that would otherwise be lost.

Your petitioners also claim as an improvement to the original machine, the following: At the summit of the machine, and underneath it, there are placed two rings, through ADAM LINHART. I SAML. MoCLAIN. Witnesses:
